HELP

I finally made room on my hard drive and tried to up load files from my new 5d mk iii. Jpeg no problem but would not recognise raw files. I did some research on internet and it says that CS5 and CS6 should read 5d iii files and I have CS5. Anyone have any clues as to what I'm doing wrong? Usually I plug in camera and upload files using bridge and then process in ACR then Photoshop.
